Question

How many orbitals are there in $\mathrm{K},\mathrm{L},\mathrm{M}$ and $\mathrm{N}$ shells? what are they?

Answer 1

1. A mathematical function that describes the wave-like character of an electron is called an orbital.
2. The pathway followed by the electrons which revolve around the nucleus of an atom is known as a shell.
3. The shell which is present close to the nucleus is called '$\mathrm{K}$' shell and the second shell is found to be a little bit far away from the nucleus is called $\text{'}\mathrm{L}\text{'}$ shell.
4. The third shell is called $\text{'}\mathrm{M}\text{'}$ and the fourth shell is $\text{'}\mathrm{N}\text{'}$.
5. The number of orbitals for $\text{'}\mathrm{K}\text{'}$is only $1$ and it is $\text{'}\mathrm{s}\text{'}$, there are $2$ orbitals for $\text{'}\mathrm{L}\text{'}$shell and they are $\text{'}\mathrm{s}\text{'}$and $\text{'}\mathrm{p}\text{'}$.
6. There are $3$ orbitals for $\text{'}\mathrm{M}\text{'}$ shell and they are $\mathrm{s},\mathrm{p}$ and $\mathrm{d}$ whereas for the $\text{'}\mathrm{N}\text{'}$ shell there are $4$ orbitals and they are $\mathrm{s},\mathrm{p},\mathrm{d}$ and $\mathrm{f}$.
